One of front and rear end portions 35, 36 of a crotch panel 12 is attached to respective non-skin-facing sides of elasticized waist panels 11 by the intermediary of bond-regions 60, 61 respectively including non-bond regions in midsections thereof. The waist region 14 to which the one end portion 36 is attached is formed at the midsection thereof with a separable portion 19 extending in a longitudinal direction Y when a wearing article 10 is put on the wearers body.
